Sarah is currently sporting an edgier raven-haired look. The new brunette, who starred in the 2007 St Trinian's comedy, said she doesn't want to get typecast as "your typical blonde heroine".

"There's nothing wrong with getting a bit more down and dirty, and looking a bit more shoddy and roughed up for a role," she said.

Sarah - the face of the HTC Incredible S smartphone in matte black from The Carphone Warehouse and Best Buy - added: "It's nice to show off a different side when it comes to your acting and be a bit grittier.

"Ideally I prefer those kind of roles. I'm not averse to comedy or having a laugh but I kind of want to do stuff that's a bit grittier first."
